650V AC Drive
Application 5: PID
A simple application using a Proportional-Integral-Derivative 3-term controller. The setpoint is taken from AIN1, with
feedback signal from the process on AIN2. The scale and offset features of the analogue input blocks may be used to
correctly scale these signals. The difference between these two signals is taken as the PID error. The output of the PID
block is then used as the drive setpoint.
